NYU, Qunnect Achieve 10-Mile Quantum Network Test

The pioneering achievement represents a significant advancement for network protocols. It also presents opportunities for financial services, telecom entities and critical New York infrastructure to further explore quantum networking solutions.

For the test, Qunnect and NYU’s Center for Quantum Information Physics transmitted entangled photonic qubits, at a rate of 15,000 pairs/second via a fiber optic cable, achieving a 99% uptime. The project used quantum entanglement, a sensitive state that demands stringent monitoring. 

In prior attempts, scientists could only achieve brief operational periods for quantum networks. This latest accomplishment relies on Qunnect’s GothamQ network, which

“This foundational achievement will pave the way for future expansion of an underground, high-capacity fiber optic network connecting NYU with New York City’s other institutions, including financial and banking centers and technology companies, through quantum communication and computing,” said NYU vice provost for research and chief research officer Stacie Grossman Bloom.

The collaborative effort between NYU and Qunnect has pushed the boundaries of quantum networking and showcased the tangible benefits it can bring to urban centers like New York. 

“This test represents the next step in building a quantum network that engages clients in critical industries that need to future-proof their security,” said Qunnect CEO Noel Goddard.

Quantum networks could significantly bolster data transmission security, enhancing communication, computing and cybersecurity capabilities. According to Qunnect, its quantum networking approach could provide robust defense mechanisms against network tapping, making intrusions easily detectable.
